and Caragli Lake. In addition to the Lee, wMcli forms tie boun- 

 dary between Worth, and South Cork, there is only one considerable 

 river, the Bandon. In this district the insular climatic conditions 

 characteristic of Ireland, moisture and mild and equable temperature, 

 reach their maximum. There is a marked southern element in the 

 flora, but considering the elevation of the mountains, the Highland 

 type is but poorly represented by 24 out of the 41 species occurring 

 in Ireland, the lofty mass of the Eeeks yielding but 12 of these. 

 The Hieracia are conspicuously rare here, as they are generally 

 throughout the south of Ireland. No less than 10 species are 

 peculiar in Ireland to this district, and of these three, Saxifraga 

 Qeum, Arhutus Unedo, and Simethu licolor, reach here their 

 extreme northern limit for Europe.
